My invention relates to a new and useful ground connection and consists of'anew and useful means for connectingthe, same with a pipe, rod or other suitable conductor.

. t further consists of other novel'features of construction, all as will be hereinafter fully set forth. I

eferring to the drawings, I have found in practice in the ground connectlons for elec:

trical conductors now in use that owing to the arrangen ent of the tightening means, the pipe or other support to which the connection is fastened, 1s apt to be destroyed or injured. My invention is designed to o'ver come this defect and to provide a new and novel connecting means which can be quickly and easily operated and in the drawings I have shown a construction for carrying out my invention but it will be evident that the. arrangement of the parts may be varied and other instrumentalities may be employed witch will come within the scope of my inveirtion and I- do not therefore desire to be limited in every instance to the exact con:

, struction as herein shown and described but which passes through suitable openings in ar desire to make such changes as may be necessary.

1 desi nates the body of my connection having the side lates 2 and 3 and to one of which is adapte to be'connected aband 4 in any suitable manner. I have shown the band having an o ening 5 therein through which passes a t eaded bolt or screw 6 the side walls 2 and 3, said bolt being a ed to hold the end of the band 4 in proper po- Patented Dec. 22,-1908.

sition withrespect to the proper side plate, I

which in the present. instance I have shown as 2. Theband 4 is preferably flexible and of any suitable metal or other good conducting material. At a suitable oint in the opposite plate from that to whic the end of the and 4 is connected, in the present instance the side plate 3, I provide the slot or opening 7 through which the free end of the band is adapted to be passed from the inside.

8 designates an eccentric plate or look which is mounted upon the screw or pin 6,

which passes through an opening 9 in said plate, it being noted that said opening is preferably above the center of the plate, and that the lower portion thereof is adapted to contact with the portion of the band 4, after it has assed through the opening 7 whenthe said p ate Sis in its normal position.

10 designates a nut which is adapted to be placed upon the end of the screw or pin 6 and etween which and a nut 11, is adapted to be secured, a conductor 12, a nut 13 holding the parts in position. i

The operation of the device will be readily apparent: 'When the nuts 13, 11 and 10 are loose, the plate 8 can be swung around upon the pin or screw 6 from in 'front ofthe opening 7. The band 4 is placed around the pipe or conductor 14 and the end thereof is passed beneath the side plate 3 of the body portion 1, and through the opening'7 from the inside, the end 15 of the band extending outwardly. The plate 8 is now returned to its proper position in front of the o ening 7 and the lower.

portion thereof abuts t 1e portion of the band 4 in front of the plate 3. By tightening the. screws the plate 8 is forced against the band holding or locking the same firmly in position while the two side plates 2 and 3 are compressed or caused to approach each other and movement of the free end 15 of the band is prevented by reason of its engagement with body portion, a flexible band having one end opening thereof connected with a suitable part of said body portion, a lock carried by said body and adapted to hold the free end of said band in engagement with said body portion and means for compressing said body portion for tightening the hand around a suitable support and for holding said lock in proper position. a

3. In a device of the character described, a body portion, plates thereon, a band adapted to pass around a suitable support, one end of said band connected with one of said plates,.

means for drawing said plates together, and a lock carried by the opposite plate for connecting the free end of said band with the plate.

4. In a device of the character described, a body portion, side plates, a band having one end secured'to one of said side plates, means for drawing said side plates together, an in one of said side plates through which the other end of the band is passed, and a lock carried by said-plate adapted to 'lock said free end with respect to said plate.

5. In a device of the character described, a body portion, a flexible band having one end secured to one of said side plates, a screw passing through said side plates for coinpressing the same, an opening in one of said side plates through which the free end of the band is passed and an eccentric plate or look carried by said side plate adapted to be swung out of position for allowing the free end of the band to be and suitably actuated for locking said free end to said side plate.

6. ha device of the character described, a

body portion, plates thereon, a band having an opening, a screw passing-through said side plate and said opening in said band, a plate orloek mounted on said screw, one of said side plateshaving an opening therein through which the free end of the band is adapted to pass, and a nut carried by said screw adapted to be tightened for. compressing the side plates and for holding the look in proper position for locking the free end of the band to the plate, whereby the said band is tightened around the support.

7. In a'device of the character described, a body portion comprising topand side plates, a flexible band fastened thereon, a bolt or screw passing through said side plates, one of the side plates having an opening therein through which the free end of the band is adapted to pass, a plate carried by said bolt and adapted to. clamp the free end oi the band against said body portion, and nuts carried by said bolt for compressing the side plates, holding the free end of the band in position and drawing the band tight around the support.
